Abstract: The invention concerns a cryptographic module and method of setting such a module to sign data, the method comprising: creating (22) inside the module a signing identity (SID) with asymmetric key pair; generating (24) inside the module a signing asymmetric key pair (SK USER , PK USER ); using the signing identity key (SK SID ) to generate inside the module a first certificate (PK USER Cert) certifying the signing key; and sending (27b) said first certificate to a certification authority (7), the signing secret key (SK USER ) being for use in computing a signature of data with an asymmetric algorithm.

Abstract translation: 本发明涉及一种将这种模块设置为签署数据的加密模块和方法，所述方法包括：在模块内部创建具有非对称密钥对的签名标识（SID）（22）; 在模块内生成（24）签名非对称密钥对（SK USER，PK USER）; 使用签名身份密钥（SK SID）在模块内部生成证明签名密钥的第一证书（PK USER Cert）; 并且将所述第一证书发送（27b）给认证机构（7），所述签名密钥（SK USER）用于计算具有不对称算法的数据签名。
